Source Connections Introduction

The SSD-66 (5.1) is uniquely designed to provide you with several installation options, espe-
cially regarding the source components connected to the unit.
Audio•Video Inputs
The SSD-66 (5.1) has a total of eight audio inputs (4 digital) and four video inputs. All of the
video inputs are composite video. Four of the audio inputs are analog. Three audio inputs
are digital, two coax and one optical. The digital inputs can be used for either AC-3 Digital 5.1
sound or digital PCM audio. The other audio input is a multi-pin input which is for six channel
digital audio from the DTS-1. The correlation of audio and video is programmed in software.
Thus, there is great flexibility when connecting source components to the SSD-66 (5.1).
Acoustical Parameters
When a specific Input Label is selected, in addition to switching the audio/video inputs, the
SSD-66 (5.1) will automatically call up a preprogrammed Acoustical Parameter. This Acous-
tical Parameter is programmed directly on the front panel of the SSD-66 (5.1) and will include
active filters, active speakers, a specific surround sound mode, PCM scale, etc. Thus, when
switching from VCR to CD, the SSD-66 (5.1) can be set to automatically go from Pro Logic to
Stereo Bypass mode, change the active speakers in use, change the filtering, etc. Further-
more, the adjustable PCM scale permits you to maintain equal volume levels when changing
from one source to another.
Input Labels
The SSD-66 (5.1) has a total of fourteen Input Labels. Each Input Label has a preassigned
(default) audio and video input which is programable. Furthermore, an Acoustical Param-
eters is specific to each Input Label. Thus, when a specific Input Label is selected, from either
the SSD-66 (5.1)'s front panel, an ADA keypad (3000 Series Control), ADA SSD-66 IR Re-
mote Control, or computer based touch screen system, the corresponding audio and video
inputs are switched in the SSD-66 (5.1) and the programmed Acoustical Parameter, for that
Input Label, will engage.
Note
While the SSD-66 (5.1) has a total of fourteen Input Labels and only eight Audio Inputs, the
additional Input Labels exist to permit you to have one source component assigned to more
than one Input Label.
Example
A TV tuner can designated with two Input Labels. One will be labeled TV MONO and the
other TV Surround. When the user selects TV SURRND , the SSD-66 (5.1) will access the
Analog Audio Input Two and Video Input Three (for example) and engage the programmed
Acoustical Parameter which would include all speakers active, the Pro Logic mode, and sev-
eral other specific filters. When the user selects the TV MONO Input Label, the same A/V
Input is called with a totally different Acoustical Parameter that might include only the front
speakers as active, the Phantom surround mode, and different filters.
Defaults
The SSD-66 (5.1) has several default parameters. The primary default refers to the setup in
which the SSD-66 (5.1) is shipped. Additional default parameters are programmed per Input
Label or for the overall setup of the system.
